A young artist, a graduate student Yuri Dyachenko leaves the Institute of Arts, defending his right to freedom of creativity. Yuri manages to arrange his first solo exhibition. However, his paintings turn out to be incomprehensible to a wide audience. This becomes one of the reasons for the spiritual crisis of the painter. The hero's relationship with the outside world is difficult...

The plot is not developed; in the film we see a man (he) and a woman (she) who, in fact, are neither connected nor familiar with each other; they casually met in hospital. "She" (Viktoria Tolstoganova) does not see that she is in danger in connection with her plan to use a tape with illegally made recordings as compromising evidence in court. "He" (Il'ia Shakunov, an actor of the Petersburg TYuZ) is a gay translator who, after the random meeting with her, is pursued by her image which frequently pops up in front of him. As a consequence, his relationship with a young boy no longer satisfies him. Both he and she lose sight of the meaning of life, because of their own inability to see others and to see love, as perception relies on proximity instead of distance.
